ELASTOMERIC BEARINGS AND SLIDING DEVICES

 

Structural elastomeric bearings help increasing the natural period of the structure by extending the dominant values liable to be produced under the seismic activity. They contribute to the reduction of seismic forces and act as natural springs which re-centre the structure after an earthquake.

Sliding devices are usually used in combination with structural elastomeric bearings and are employed to reduce the movements of the structure subject to the earthquake by exposing themselves to the seismic energy. Application field: massive, circular structures such as liquefied gas tanks and nuclear power plants.
